Need Lesson For Jesu, Joy Of Man's Desiring (classical)

I must be missing something as this is a very popular piece. I didn't see a lesson here. Can someone point me in the right direction if there is one?

Thanks

Anyone know where I can get this?

S = Slap What Does This Mean?

I'm working on one of your lessons and the S is above every note. Don't know what this means.

Classical Fingerstyle Beginner Needs Help

Need help for classical for the beginner. I have viewed all the lessons that are Level 2 to 3 and am practicing these lessons. There seem to be only a handful. What I would like is more help/suggestions for my level. Although I'm just starting classical, I have played for several years. Now I'm just wanting to go deeper. I practice arpeggios daily. Mainly the two pieces I'm working on are Greensleeves and Carulli Waltz. Also the Carcassi arpeggios. I look at some of the Level 3's and they are way beyond my ability now.

I have a Epiphone PR5E and not a classical guitar at the moment. But I am hoping to get one as soon as possible.
